IPC: G01J1/02
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To obtain a light source having a uniform light quantity distribution and without having directivity by using a laser light, making an opening of a light entrance part small and setting an optical path dispersion optical system minutely vibrating at a high speed at the light entrance part. SOLUTION: The integrating sphere 10 is used in combination with a laser light source 14 and has an optical path dispersing optical system of a combination of a light-bending mirror 19 and a piezoelectric element 20 opposed to an entrance part 11. An opening of the entrance part 11 is made small and the interior of the integrating sphere 10 is formed of a material of good dispersion properties. The light-bending mirror 19 is mechanically vibrated when a laser light 21 is bent by the mirror 19 and brought into the entrance part 11. Because of this arrangement, the laser light 21 is guided into the integrating sphere 10 through the entrance part 11 from various angles in a minute range, scattered many times in the sphere and projected from a projection part.  A test body is observed by a projected light having a vibration component of the light-bending mirror 19 integrated, and therefore in-plane uniformity of the projected light is improved and a light source without directivity is obtained.
